Sometimes bridges are fascinating ... most people visualize them from the "topside," that is the part of the bridge that's there to be walked, driven, or carried upon. After all, bridges are meant to bring things together from places or people that are NOT together. Not surprising then that the "functional" part of the bridge is the one that people appreciate for form and function. But there's the "under" the bridge part, too, and everyone knows that something is down below but most don't care or don't have the time to look. In many metropolitan areas, the major intersections of highways and roads are winding cloverleafed, twisted, mazes of bridges and...under bridges. Sometimes filled with trash, water runoff pools and puddles, and once in a while camps of homeless folks. But not in Harper's Ferry where I took this shot under the railroad bridge. Water runoff and tourists.
